2 Claims.

This invention relates to package wrappers or jackets of particular value as coverings or wrappings for glass bottles where the bottle contents may have to be protected from the light, although the wrapper may serve also or only as a protection against mechanical injury to the bottle or other article packaged within it. A particular wrapper or jacket chosen for illustration of the invention is designed to enclose an ordinary type of milk bottle Within which chocolate milk may be contained, thereby to protect the chocolate from oxidation or deterioration as might be the case were the same exposed to the light.

One of the principal objects of the invention. is to provide a simple, economical and effective wrapper or jacket of the character mentioned which may be composed of fibrous sheet material such as a light, medium or heavy paper or paperboard or strawboard or other similar material.

Another one of the principal objects is to pro-:-

vide a wrapper so constructed that it may fit fairly and snugly about the body and upper or neck portions of a bottle or other container or article for which it may be designed, the arrangement and construction also being such that the" wrapper may be slipped over and removed from the bottle or other article with a minimum of time or effort.

Still another object is to provide a wrapper or jacket of such construction that it may be folded Many other objects as well as advantages, uses and adaptations will become apparent from the following description and claims as well as from the drawing, in. which a preferred type of construction is exemplified.

Fig. 1 is a plan or developed view of a blank cut and scored and to which adhesive has been applied, in readiness for folding or rolling into the final shape;

Fig, 2 is a front view of the wrapper or jacket in its final position about an ordinary type of milk bottle, with the overlapping edges of the wrapper disposed in front, the dotted lines indicating the areas over which adhesive is applied.

Fig. 3 is a longitudinal section taken along the section line III-III of Fig.2; and

Fig. 4 is a view of the wrapper folded and secured and flattened down for purposes of storage orshipment.

The illustrated form of the invention is that one of a number of forms which is at present preferred and in itself is susceptible of modification as will be appreciated by those becoming familiar with it and its applications. The blank of Fig. 1 may be cut from a single sheet of material, preferably a medium weight paper or a light. weight paperboard, and comprises a lower portion 2. of generally rectangular shape and an upper portion 3 of arcuate shape, the two portions being integrally joined together along the relatively straight upper edge 5 of the lower portion and the relatively convexly arcuate lower edge 6 of the upper portion as indicated at t. The length of the integral connection or juncture between the upper and lower portions, as measured along the lower edge 6 of the upper portion or the upper edge 5 of the lower portion, preferably is such as to provide a reasonable amount of strength be tween the portions thereat to hold them together While being a relatively small percentage of the total length of either of such edges. The lower edge 5 of the lower portion preferably is parallel to the upper edge 5 and, similarly, the arcuate upper edge 6' preferably is concentric with the edge 6.

The lower portion 2 is designed to wrap or enclose the lower portion of a common type of milk bottle or the like and to such end is intended to be folded or rolled into a substantially cylindrical shape, with the marginal portion adjacent to the edge I lapped upon and secured by an adhesive (shown conventionally in Fig. l) to a narrow marginal securing strip or portion 8 extendin along theopposite edge 9. The strip 8 is extended. in the form of a securing tab H projecting upwardly beyond the upper edge 5 of the lower portion 2 for a purpose to be described, but the edge 1 laps the margin 8'with the ends of the upper edge 5 and the lower edge 5 in register, respectively, with one another so that the tab H projects above the upper end of the cylinder when formed. Depending upon the direction of folding or rolling of the blank and whether the observer views the cylinder from the inside or outside, the edge 1 may be considered to underlap or overlap the strip 8; preferably the edge I overlaps the marginal strip 3, viewing the exterior of the cylinder.

In order to facilitate the rolling or folding of the lower portion 2 into cylindrical shape, especially when paperboard is used, it may be scored along a plurality of spaced lines l2 extending transversely of the length of the portion 2 or longitudinally of the cylinder and substantially parallel to its axis. In a similar manner, the upper portion 3 which may be considered, in the blank form of Fig. 1, to be the developed state of a right section of a truncated cone, is scored along lines I 3, making substantially equal angles with one another at and generated from a point (in space) constituting the top or apex of the cone of which the portion 3 is a truncated part. Preferably the spacing between the lower ends of any pair of adjacent score lines l3, that is, where adjacent lines I3 and the edge 6 meet, is equal to the spacing between the upper ends of correspondingly adjacent score lines [2.

While at one side of each of portions 2 and 3, the free parts of their edges and 6, measured from their juncture at the portion 4 to the side edges 1 and I4, are substantially equal and preferably are divided into an equal number of respectively similar panels by reason of score lines I2 and [3, the other side of the conical upper portion preferably extends (at its uper edge 6') for a length greater by one panel than the side of the lower or cylindrical portion 2 at the same side of the juncture 4. The arrangement preferably is such that the edge l5 of the upper portion 3 lies in alignment with the edge 9. Adhesive may be applied along a marginal strip I 6 in alignment with and on the same side of the blank as the adhesive on the securing strip 8, thereby to facilitate the adhesive applying and blank folding operations. The edge I4 may underlap or overlap the adhesiv carrying margin [6, de-

pending upon the side of the blank to be presented to the exterior, but should correspond in arrangement to the arrangement of the edges 7 and 9 to one another, as will be obvious.

The two portions of the blank when so prepared may then be folded or rolled correspondingly to the shape shown in Fig. 2 in the form of a cylinder adapted snugly to receive and fit about the body of a botttle l1 and, with the upper conical portion 3, adapted to be disposed snugly about the neck part of the bottle. Preferably the upper portion 3 is so designed and proportioned that the upper edge 6 thereof will give sufficiently to pass over the portion l8 of I the bottle top edge having the greatest diameter,

so that the wrapper will be held in position on the bottle against accidental displacement.

The upper portion preferably is folded so that the two adjacent panels to which the adhesive is applied (strip IE) will underlie the pair of adjacent panels adjacent to the edge I4, as indicated in Figs. 2, 3 and 4. Similarly, that panel of the lower portion which is adjacent to the edge 1 is overlapped on the securing strip 8 With the edge I substantially coinciding with the score line H defining strip 8. The tab H is disposed on the inside of the conical portion with the adhesive carrying face thereof against the inside face of that adhesive carrying panel of the upper portion which lies immediately thereabovc. The resultant product may then appear as shown in either Figs. 2 and 3 or Fig. 4., depending upon the method by which the forming or folding is carried out.

If the wrappers are to be shipped to a remote point of use, it may be preferable to fold the upper and lower portions so that each portion v lies flat as indicated in Fig, 4, To that end, the

procedure may be to fold the two ends of the upper portion toward one another into proper overlapping and underlapping relationship on score lines 13 specially marked A and B (Fig. 1) and down flat against the panels between lines A and B, the ends of the lower portion being similarly folded on score lines l2 specially marked A and B. In this flat condition, large quantities of the wrappers may be stacked upon one another and shipped with a maximum economy of space, yet at th place of use may readily be opened, shaped and slipped over the tops of and into position about bottles and the like.

The invention being susceptible of other embodiments and being adaptable by modification to a variety of purposes and uses, it is desired that the same be limited only by its spirit and the scope of the appended claims.

I claim:
